You can specify the time period for which you want to retain deleted files in the backup cycle. A deleted file is available for browse and restore from the latest backup cycle.
Subclient retention settings determine when the retention for the storage policy copy starts for deleted files. Storage policy copy retention can start immediately or be delayed for a specified period of time. Delaying the application of the storage policy copy retention on deleted files allows you to browse and restore the deleted files from the latest backup cycle.
Synthetic full backups manage the application of subclient retention settings. Files that exceed the subclient retention criteria are not included in the next synthetic full backup.
You can also retain additional versions of your file, including the latest version, when you perform a synthetic full backup. For more information, see Configuring Retention for Additional File Versions.
